Sumi Sakurasawa is shy. Even simple things, like ordering a donut or calling out to a stranger that they've dropped something, paralyze her with fear. Her plan to fix it? Become a "rent-a-girlfriend" and make some cash while she practices her people skills! But raising the stakes even higher might not be the foolproof solution she thought it was... And even worse, she needs five-star reviews to keep her new gig, and that means no freezing up or freaking out on a date... How is that even possible?!
